How do modern heating systems work?
Basic principles Radiators Transfer heat from very small & very hot surfaces (750C) to the room (200C). High rate of convection. UFH Transfers heat from a surface slightly warmer than the room (290C to 200C) Very high rate of radiation. Natural, comfortable warmth.
Modern Underfloor Heating Mainly warm water Mainly warm water High tech plastic pipe in or just below floor High tech plastic pipe in or just below floor Water is O C Water is O C Forms to suit most floor constructions Forms to suit most floor constructions Well proven controls Well proven controls Economical to run Economical to run Reliable, long lasting Reliable, long lasting Maintenance-free Maintenance-free
Solid Floor Construction
Pipe set in place before screed is laid
Suspended Floor Construction
Cross-batten wooden suspended floor
Floating Floor Construction
Floor Cross Section
S Plan layout
Familiar Technology 20°c
How do Radiators Work? Stratification leads to higher temp. and thus high heat loss 27°C 20°C 19°C 17°C 50°C 17°C HIGH HEAT LOSS THROUGH WINDOWS
How does UFH Work? Just like one big low temperature radiator 27°C to 29°C 20°C
Energy Savings with Underfloor Heating No hot air in front of glass No hot air in front of glass = Less heat loss through window No hot air at ceiling level No hot air at ceiling level = Less heat loss through ceiling & wall Lower air temperature for same comfort Lower air temperature for same comfort = Reduced number of air changes Uses lower water temperature Uses lower water temperature = Lower transmission losses Options to use non-fossil fuel heat sources Options to use non-fossil fuel heat sources and boilers in condensing mode
Advantages of UFH Advantages of UFH Very comfortable Very comfortable No hot heads or cold feet No hot heads or cold feet Does not promote floor draughts Does not promote floor draughts No drying of the air No drying of the air Reduced dust levels Reduced dust levels Unobtrusive Unobtrusive Walls left completely clear Walls left completely clear Floors and walls are easier to clean Floors and walls are easier to clean
Other Advantages of UFH Quiet No creaks and groans, especially in solid floors Safe No hot surfaces - important to HSE No sharp edges to cause injury This is the Ultimate low surface temperature radiator Nothing to vandalise (In Sweden only UFH is allowed, by law, in Children's nurseries)
Observation Radiators were a great advance when the alternative was to have a open grate in every room... and now UFH is the ultimate radiator
Summary Underfloor Heating today is:- Clean and green Comfortable Invisible Quiet Safe Energy-efficient Maintenance-free UFH has come a long way, and is right for the UK too!
WHAT CAN DO FOR YOU?
We offer a complete package Quotation Design Installation Commissioning Full system documentation 25 year warranty After Care Support
